I read she shot 1 and they both ran. One made it to the ditch along side the rode.
I hope so. It would be bad for her if he was already outside when she shot him.
Just an amateur writer here, but IMHO this was horribly written, and I can't help if that was on purpose. Common sense says she shot him in the home he ran and ran out of adrenaline etc and died from the shot, they make it sound like it was a shooting galley off the back door or something shooting him in the back, or at least that is the impression they want to leave IMHO....
